Abstract: Highlights•We study the underlying geometry behind line projection in conical and spherical non-central catadioptric cameras.•The first automatic line-image extraction method for calibrated non-central catadioptric cameras.•The paper opens the possibility of obtaining 3D information from lines in a single non-central view.•We propose a new measure (“effective baseline”) of the 3D reconstruction quality of a 3D line from the minimum set of rays.
